Great to have you here Josh!

Im still young and relatively ignorant to many of the topics discussed here, but if you will just bare with me, as i know you will, i might, in time, actually learn to add something to the site.

Most of all as you read and participate in the community, don't be afraid to question common beliefs here, that's where the contribution is likley to be there I think. Also if you plan on going through one or more of the sequences systematically consider finding a chavruta.

I think i have a fair grip on the basic points of rationality as well as philosophy, but i am sorely lacking in terms of math and science (which can't be MY fault obviously, so I'll just go ahead and blame the public school system)

To quote myself:

As for relevant math, or studying math in general just ask in the open threads! LWers are helpful when it comes to these things. You even have people offering dedicated math tutoring, like Patrick Robotham or as of recently me.

Also a great great resource for basic math are the Khan Academy videos and exercises.
